ossBucket.setBucketTokenGen(new TokenGenerator() {
            @Override
            public String generateToken(String httpMethod, String md5, String type,
                                        String date, String ossHeaders, String resource) {
                String content = httpMethod + "\n" + md5 + "\n" + type + "\n" + date
                        + "\n" + ossHeaders + resource;
                return OSSToolKit.generateToken(_accessKey, _accessSecret, content);
            }
        });
